AZ23C7V5-7

Overview

The AZ23C7V5-7 is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common anode configuration with two independent Zener elements sharing a single terminal. The nominal Zener voltage is 7.5 V, operating within a range of 7.0 V to 7.9 V at a test current (IZT) of 5.0 mA. Maximum power dissipation is rated at 300 mW, supported by a typical thermal resistance from junction to ambient air of 417 °C/W. The device exhibits a maximum Zener impedance (ZZT) of 7.0 Ω and a typical temperature coefficient of +0.050 %/°C. Reverse leakage current is limited to 0.1 µA at a reverse voltage of 5.0 V.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
• Common anode configuration allows for simplified biasing and routing in dual-channel applications.
• Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.
• Qualified to JEDEC standards for high reliability and suitable for automated insertion processes.

Applications

• Voltage reference circuits requiring stable dual-channel regulation.
• Clamping and protection stages for sensitive input/output lines.
• Biasing networks in analog signal processing modules.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm commercial versus automotive qualification levels. Ensure that the selected variant matches the required packing quantity and carrier type for your assembly line equipment. Cross-reference the date code marking on received components to validate manufacturing timelines and storage conditions prior to soldering.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required in a low-profile SOT-23 footprint. Evaluate the 300 mW power dissipation limit against the expected thermal environment to ensure operation remains within the specified -65°C to +150°C temperature range. Confirm that the 7.0 Ω maximum impedance meets the dynamic regulation requirements of the target application circuit.

Part Context

This part belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same mechanical outline and electrical testing parameters. The standard commercial version utilizes the -7-F suffix, while automotive-grade variants are available with a Q-suffix for applications requiring AEC-Q100/101/104/200 qualification.

Replacement Considerations

The DZ23C7V5 is the common cathode equivalent within the same product family. Verify pinout compatibility if substituting between common anode and common cathode configurations, as the internal polarity differs.
